Answer:

when you set up 3 * (1/3), you're both multiplying and dividing by a 3. these two cancel out, and you're left with one. 3 *(1/3) is simply 1.

When you set up 3 * (1/3), you're both multiplying and dividing by a 3. these two cancel out, and you're left with one. 3 *(1/3) is simply 1.

12 * (1/3), when you set it up, doesn't cancel out the same. multiply straight across the top (12 * 1), then divide by the bottom (3). 12/3 = 4, so 12*(1/3) is 4.

9 * (1/9) gives you the same result as the first one. the multiplied 9 and the divided 9 cancel out, and you're left with 1.

Which expression is equivalent to ? Assume.
nikdorinn [45]

Answer:

2. -2x^{8}y^{18}  

Step-by-step explanation:  

We have been given an expression \frac{10x^{6}y^{12}}{-5x^{-2}y^{-6}} and we are asked to find equivalent expression to our given expression.

Using fraction rule \frac{a}{-b} =-\frac{a}{b} we can write our expression as: -\frac{10x^{6}y^{12}}{5x^{-2}y^{-6}}. 

Upon dividing 10 by 5 we will get,

-\frac{2x^{6}y^{12}}{x^{-2}y^{-6}}      

Upon using exponent property for quotient (\frac{a^{m}}{a^{n}} =a^{(m-n)}) we will get,  

-\frac{2x^{6}y^{12}}{x^{-2}y^{-6}}=-2x^{(6--2)}y^{(12--6)}    

-2x^{(6+2)}y^{(12+6)}

-2x^{8}y^{18}        

Therefore, our expression simplifies as -2x^{8}y^{18} and 2nd option is the correct choice.

Ming wrote the table of points below.
anzhelika [568]

Answer:

Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin

Step-by-step explanation:

Given

x - y

5 - 10

10 - 20

15 - 30

Required

Determine if the data are proportional

The dataset is small; so, we can derive the relationship by observation.

By observing the x and y values, the relationship is:

y = 2x --- i.e. multiply x values by 2.

This is further proven by:

y = 2 * 5 = 10

y = 2 * 10 = 20

y = 2 * 15 = 30

y = 2 * 0 = 0 --- the origin

Hence, the dataset is proportional and it passes through the origin.

From the Pascal's triangle, take the correct level. Use it to write the binomial expansion. Or use nCr.
(x+y)^n
Remember that the powers of x start at n, and that the sum of the x and y powers is always n.
